How To Update LG Optimus 3D P920 with Ice Cream Sandwich Android 4.0 Firmware

Procedure to update Ice Cream Sandwich 4.0 on LG Optimus 3D:

  • First up you need to download the Ice Cream Sandwich 4.0 Firmware Zip to your computer. Once it’s downloaded, you will now need to proceed to connect the phone to the computer using the USB cable which you got at the time of purchase.
  • So, once you are done with the downloading, you need to copy this downloaded zip file as it to your phone without modifying or renaming the file. Once you copy the same, you now need to download the ROM Manager application in your phone.
  • The ROM Manager can be installed from the Android Market Place. Now, once you downloaded and installed the ROM Manager application, you need to open the same and then select the option of “Flash Clock Work Mod Recovery” to flash the same.
  • Once you are done with this, you now need to create a backup of your current ROM which you can do by selecting the option of “Backup Current ROM” in the ROM Manager so that you can then revert back to the Stock original version just in case if you face any issues with the new Ice Cream Sandwich ROM as its in the beta stage.

    I did all steps mencioned here, step by step, or from begin to the end. The diference that I saw is all pictures posted on this website is very very diferent from the phone, I do not why.

    I agree with Vortecduramax, Bara 93, tyler wewsecv, almost said the same thing, I just don’t know what is wrong with KING 3D ROM, even I cannot find out its official website. Now, my phone is broken ’cause of it. It does not power on anymore.

    I’ll send it to Lisbon, Portugal, to be repaired for free without any fee/charge/fare.

    I just wish much luck for who has it on phone and it runs normally, my best.
